Now days a trend of International Schools has started everywhere. Does it really help or just show off money ?

I think this is a type of business.

yes ,they are helping the country andhelping the students

Inspite of all these international or national schools. We always fail to educate the kids. Its all the same.

type of business

Certainly, it helps; not only individuals but relevant institutions.

Some excellent and some are bad

Never heard of it
